GAS-TIP.

SPECIFICATION forming part of Letters Patent No. 640,686, dated January2, 1900. Application filed January 20, 1896. Serial No. 576,184- (Nomodel.)

To all whom/ it may concern.-

Beitknown that I, OSCAR MUSSINAN, a citizen of the United States,residing at Arverneby-the-Sea, in the county of Queens and State ofNewYork, have invented certain new and useful Improvements in Gas-Tipsand Methods of Making the Same, of which the following is aspecification.

My invention relates to gas-tips, and has for its object to provide ametallic gas-tip which is adapted to receive, support, and protect astable catalytic material capable of igniting gases at ordinarytemperatures; and to these ends myinvention consists in the va* riousfeatures of construction and arrangement of parts, substantially as moreparticularly hereinafter pointed out.

In order that the general principles of my invention may be clearlyunderstood by those skilled in the art sufficiently to enable them tocarry out the same, I have illustrated in the accompanying drawings onepreferred form of gas-tip made in accordance with my invention andhaveindicated the preferred manner of constructing and arranging thesame, and it will be understood that this is typical only of theconstruction and arrangement of parts, as my invention is not limited tothe details shown and described, but covers any equivalents in form,construction, or arrangement which embody any one or more of the generalfeatures or principles of my invention.

In the drawings, Figure 1 is a side view, enlarged, of a gas-tip. Fig. 2is a vertical central transverse section through the same.

Fig. 3 indicates a piece of material from which the tip is made; andFig. 4 is a sort of diagrammatic or detail drawing showing the varioussteps through which the material passes in producing a tip such as shownin Fig. 1, it being understood, of course, that other forms or shapes orembodiments of my invention may involve other steps to complete them.

This invention is intended for use in connection with a gas-tip adaptedto support and protect a stable catalytic material capable of ignitinggases at ordinary temperatures, and for this purpose it embodies somespecial features of construction and arrangement of parts, and I willtherefore proceed to describe my invention in connection with such atipthat is, one which embodies a platform or support for the catalyticmaterial and preferably also embodies a hood or protector for thematerial, thus presenting a practical and commercial gas-tip for thispurpose.

One object of my invention is to provide a tip consisting, practically,of an inner and an outer integral shell joined together and shaped intoa tip of approved and satisfactory form, the integral shells beingtelescoped or otherwise united during the manufacture.

Other objects and results will appear from the following description andneed not be specifically recited.

The tip shown in the drawings comprises a body portion A, consisting ofan outer integral shell I) and an inner integral shell 0, a headportionB, which is herein shown as of adome or semispherical form, a platformor receiver or support 0, preferably arranged at one side of the dome orhead portion, and a protector or hood D, which elements may vary indetails of construction and arrangement. I

In the present instance the body portion A is shown with the integralinner and outer shells of substantially the same contour and length, andthis is the preferred way,although it is evident that one shell need notbe of the same length or cont-our as the other; but one shell may bemore in the form of a sleeve with relation to the other shell, eitherinternal or external, as the case may be. The head portion is also shownas consisting of a single thickness of metal formed out of the innershell, and that is the preferred form, although the head may embody moreor less of the outer shell.

The platform 0 is shown as extending on one side only of the dome orhead, although, of course, it may be on both sides. It is also shown asprovided with certain prongs or extensions O, formed integral with theplatform, for the purpose of more readily retaining the catalyticmaterial in place, and while this is the preferred form other means foraccomplishing this object may be provided.

The hood or protector is shown as constituting an integral portion ofthe outer shell and embracing more or less of the head and extendingpartially over and around the platform, and this is also the preferredform, al-

though the shape or configuration may vary to best accomplish theresults in any particular tip. The hood or protector should be providedon both sides of the outer shell whenever two platforms are used.

I will now proceed to describe more in detail the manner in which Ipreferably produce the particular form of tip illustrated, and Fig. 3represents a piece of material E of any convenient thickness or size,from which the shells or cups a, Fig. 4, are punched and drawn, leavingthe openings E in the material. It will be seen that the shells or cupsa are all of a uniform size, and from these I form, by drawing, twoshells of varying size, the shell I) eventually forming the outer andthe shell 0 theinner portion of the tip. These two integral shells areof such a relative diameter that the inner shell 0 will fit tightlywithin the outer shell b, forming an absolutely-tight joint when theyare assembled as hereinafter specified. These shells are then trimmed orout so that they are of the proper or desired length, and after thisoperation they are represented at h 0', respectively, and in the presentinstance they are shown as of practically the same length. These shellsare pointed substantially as indicated at 17 the object being to changethe heads of each in such a manner that the metal will readily andwithout break or excessive strain shape itself into the succeeding andultimate forms.

So far it will be seen that the inner and outer shells have beensubmitted to substan tially the same operations and only differ fromeach other in size; but in order to form the tip illustrated the outershell I) is next subjected to rectangular and cylindrical reduction,providing a shoulder, as seen in the side and end view 5 but of coursethese particular forms will be varied to meet the reor protector. Theinner shell is also formed into the dome and platform shape, asindicated in the side and end view 0 or such other shape as theseparticular parts are to assume, depending upon the shape and size of theframe as well as upon the size and height of the platform and thecharacter of the catalytic material and other features too numerous toparticularly specify. In order that the platform may more readily retainthe cata lytic material, the prongs may now be raised upon the platform,as seen at c", and the head is then shaped so as to form a neck ordepressed ring at the lower portion of the head,-

as seen at 0 Meanwhile the outer shell 1) is tector.

tive position with relation to each other, and this is done bytelescoping them-or sliding one within the other under the requiredpressure, so that the platform of the inner shell will rest and fitwithin the confines of the hood of the outer shell, its shoulder bearingtightly against the inner shoulder of the outer shell and the entireouter cylindrical surface of the inner shell bearing closely and snuglyagainst the inner cylindrical surface of the outer shell, forming anabsolutely tightjoint between them, and this condition of affairs isbest represented in the side and end views b 0 The two integral shellsnow practically form a single tip, so joined that they are inseparablewithout destroying the entire structure and to all intents and purposesand to all appearances they are practically a single solid shell havingthe desired interior and exterior form of head, platform, and pro- Inorder, however, that the so-telescoped shells shall be perfectly uniformin length, they may be subjected to sizing and squaring operations inany well-known manner.

So far the body portion of the tip is cylindrical; but in order to givethe body portion the adjustability desirable for gas-tips, so that theywill fit the ordinary burners or pillars on which they maybe placed,this body portion is slightly tapered, as seen at b c, and this may beaccomplished by ordinary and Well-known means, under pressure in a dieor otherwise. The tip is then put through the dual operation, which isthe slotting, producing the opening B", which is properly located and ofthe desired width and depth to meet the shape and size of the flame andother requirements, depending uponthe particular use to which it is tobe put, and the tip is brought to the condition shown at b 0 It isevident that in place of the slot any of ;the usual and well-knownoutlets for gas in gas tips or burners may be provided.

quirements of the ultimate shape of the hood 1 It will thus be seen thatwhile there are a l number of somewhat minute and delicateoperationsnecessary to the carrying out and drawings, all these may be readilyaccomplished by proper tools and machinery, so that all of the tips willbe uniform and alike in all respects in all their essential features,making them interchangeable, and it is evident that the details ofconstruction can be readily varied as desired, the tools and operationsthus generally indicated being varied in accordance therewith so thatthe ultimate result can be attained.

This tip is made of malleable metal, being drawn, reduced, and otherwisemanipulated to form the tip having the desired configuration andcharacteristics from sheet metal, and while, as above indicated, variousmetals may be used, I preferably use aluminium or aluminium alloy.Furthermore, the tip illustrated and described embraces two integral IIOshells united by telescoping or sliding them one Within the other, and,further, it has certain specific features of configuration andconstruction adapting it for the particular purposes intended. From thisit will be seen that my invention is not limited to the particularmatters specifically disclosed; but

What I claim is-- 1. A gas-tip consisting of two shells, the bodyportions thereof being closely united at the neck of the tip,substantially as described.

2. A gas-tip consisting of two shells fitted closely together, onewithin the other, one of said shells being formed with a perforated
